Strange and personal question.

I'm a first time mommy and 8 weeks 2 days pregnant. This is probably going to sound really immature and just weird so just bare with me. I had to do a number 2 today and it was a rough one, required time and lots of pushing, when it was over, I had some cramping in my uterus. Can aggressive pushing and tension affect my baby? I'm scared of miscarrying since I'm early in my pregnancy so that's the reasoning for my exaggerated concern. Don't get me wrong here, I'm not asking if me pooping will make me miscarry. Thanks for reading.
